?Non-greasy and non-rancidifying ?POLISHES AND CHEMICAL SPECIALITIES: DOW CORNING 200 Fluid
is used in most automobile and furniture polishes for its ease of application,
high gloss with minimum rubbing, and a durable water-repellant film. It is also
used in many other speciality formulations, including aerosol starches and
fabric conditioners. Additional literature is available.
?ELECTRICAL/ELECTRONIC EQUIPMENT: With excellent dielectric
properties, DOW CORNING 200 Fluid can be used for both insulating and
damping applications.
?PLASTIC ADDITIVE: Small amounts of DOW CORNING 200 Fluid can be
compounded into plastic in order to impart surface slip or anti-block and to
improve the processability of the plastic.
